be動(dòng)詞的用法總結(jié)及練習(xí)題(3)
be動(dòng)詞的用法：注意事項(xiàng)
英語(yǔ)句子中，為了表達(dá)時(shí)態(tài)或被動(dòng)語(yǔ)態(tài)的需要，常常會(huì)出現(xiàn)幾個(gè)助動(dòng)詞連在一塊兒使用。也就是說(shuō)，助動(dòng)詞be會(huì)和其它助動(dòng)詞一起使用。這時(shí)候，整個(gè)句子的一般疑問(wèn)句和否定句，就不一定是對(duì)be 進(jìn)行變化了，而是以第一個(gè)助動(dòng)詞為主進(jìn)行變化。即哪個(gè)助動(dòng)詞在先，就以它為主進(jìn)行變化。例如：
[肯定句] All the wonderful birds can be found in our Bird Park. (助動(dòng)詞有兩個(gè)：can be )
[疑問(wèn)句] Can all the wonderful birds be found in our Bird Park? (移第一個(gè)can)
[否定句] All the wonderful birds can not be found in our Bird Park. (在第一個(gè)can 后加not)
[肯定句] I have been there before. (兩個(gè)助動(dòng)詞：have, been )
[疑問(wèn)句] Have you been there before?
[否定句] I have not been there before.
[肯定句] I shall be having my supper at six tomorrow evening. (兩個(gè)助動(dòng)詞：shall, be )
[疑問(wèn)句] Will you be having my supper at six tomorrow evening?
[否定句] I shall not be having my supper at six tomorrow evening.
助動(dòng)詞be，無(wú)詞義，輔助主要?jiǎng)釉~一起在句中作謂語(yǔ)動(dòng)詞。用法如下：
1. be+doing：構(gòu)成進(jìn)行時(shí)態(tài)，有現(xiàn)在和過(guò)去兩種進(jìn)行時(shí)態(tài)。如：
The girls is reading and copying the new words now.
Young Tom was always asking questions and trying out new ideas.
2. be+going to do，表示"打算或?qū)⒁瞿呈?quot;，be有現(xiàn)在和過(guò)去兩種形式。如：
We are going to plant trees in the park.
I didn’t know if she was going to come here.
3. be+to do，表示"按計(jì)劃安排將要做某事"。如：
The new shop is not to be opened till next Monday. One night an angel came to
Mary and told her that she was to have this special boy.
be動(dòng)詞的用法：there be
there be句式為：there be+主語(yǔ)部分+狀語(yǔ)部分，表示"某處存在某物"，be常用現(xiàn)在時(shí)，過(guò)去時(shí)和將來(lái)時(shí)等。如：
Oh, cool! And there are many things to see. There is even a deer park in Sanya.
There are about 80 pyramids in Egypt.
Will there be a football match in your school next week?
be動(dòng)詞的用法：實(shí)義be
可以將be視為實(shí)義動(dòng)詞，因?yàn)樗哂袑?shí)際的詞義，如"成為;做;發(fā)生;舉行;逗留;到達(dá)"等。如：His daughter wants to be a doctor for animals in her twenties.Kates birthday party
